CHININEY-COWL.

Specification of Letters Patent.

Patented Oct. 31, 1905.

Application filed February 25, 1905. Serial No. 247,359.

To all whom it may concern:

Be it known that I, BARTow A. WARLIox, a citizen of the United States, residing at Atlanta, in the county of Fulton and State of Georgia, have invented a new and useful Chimney-Cowl, of which the following is a specification.

This invention relates to chimney-cowls for improving the draft and preventing the wind from blowing downward into the sameor the entrance of rain or snow, and has for its object to improve the construction and increase the efficiency of devices of this class.

With these and other objects in view, which will appear as the nature of the invention is better understood, the same consists in certain novel features of construction, as vhereinafter fully described and claimed.

In the accompanying drawings, forming a part of this specification, and in which corresponding parts are denoted by like designating characters, is illustrated the preferred form of embodiment of the invention capable of carrying the same into practical operation, it being understood that the invention is not necessarily limited thereto, as various changes in the shape, proportions, and general assemblage of the parts may be resorted to without departing from the principle of the invention or sacricing any of its advantages.

In the drawings, Figure 1 is a side elevation, and Fig. 2 is a sectional elevation on the line 2 2 of Fig. 1.

The im proved device comprises a Hue portion 10, having a base 11 for engaging the top of a chimney, and with a hood 12, formed with laterally-extending and downwardly and outwardly inclined Hues 13 14, the upper end of the hood and the downward ends of the laterally-inclined Hues being open, as shown, respectively, at 15, 16, and 17.

Within the mouths of the lateral Hues 13 14 are disposed curved transverse deHectingplates 18 19, depending for a distance below the Hues and adapted to receive the currents of air and deHect them upward into the hood, as hereinafter explained.

Disposed within the hood above the open discharge end of the Hue 10 is an inverted-V- shaped or cone-shaped plate 20, the base-lines of the plate extending beyond the Hue 10, so that rain or snow falling into the hood will be carried into the lateral Hues 16 and not permitted to fall into the smoke-Hue 10.

Beneath the conical-shaped member 2O is a V-shaped guard-plate 21 to Hll the cavity otherwise remaining beneath the member 20,

but also assisting in the action by deHecting the rising products of the combustion laterally into the inclined Hues 16 17.

The Hue 10 will preferably be substantially square in transverse section, and the side walls of the hood 12 and the Hues 13 14 will not project laterally beyond the side walls of the Hue 10, so that a number of the devices may be arranged closely disposed side by side. This is of advantage when the device is to be employed upon chimneys having multiple Hues, as each Hue may thus be easily supplied with an independent cowl, as will be obvious.

With a device thus constructed the smoke, gases, and other products of the combustion rising through the Hue 10 are deHected by the V-shaped plate 21 and carried around the coneshaped member 2O and exit at the open upper end 15 of the hood 12. In the meantime the currents of air entering at the lower open ends of the inclined lateral Hues 16 17 are carried upward alongside the members 2() 21 together with the smoke and gases, and thus materially accelerate the draft of the chimney, while at the same time the lateral movements of the air are effectually prevented from causing downdrafts in the same by reason of the peculiar form of the cowl The curved deHector-plates 18 19 perform an important function, as they receive the aircurrents blowing laterally against them and turn them upwardly and carry them past the upper end of the Hue 10, and thus eifectually prevent any tendency of the currents to blow downwardly into the chimney.

The device is simple in construction, is inexpensive to manufacture, and can be adapted to any form or sizeof chimney or smoke-stack.

Having thus described the invention, what is claimed is- A ventilator comprising a Hue having means at one end for connection to a chimney and with a hood extending above the same and.

IOO

open at the upper end, said hood having oppositely disposed lateral branches inclining downwardly and outwardly therefrom, a coneshaped deflector within said hood above said Hue, and curved deHector-plates disposed within the open lower ends of said inclined branches and transversely of the same.

In testimony that I claim the foregoing as my own I have hereto aHxed my signature in the presence of two witnesses.
